Answer: 58 degrees
Explanation: 180-122=58
Answer:
![x=\pm5,\ x=\pm4i](https://tex.z-dn.net/?f=x%3D%5Cpm5%2C%5C%20x%3D%5Cpm4i)
Step-by-step explanation:
![-3x^4+27x^2+1200=0](https://tex.z-dn.net/?f=-3x%5E4%2B27x%5E2%2B1200%3D0)
Divide each side by ![-3](https://tex.z-dn.net/?f=-3)
![x^4-9x^2-400=0\\x^4-25x^2+16x^2-400=0\\x^2(x^2-25)+16(x^2-25)=0\\(x^2-25)(x^2+16)](https://tex.z-dn.net/?f=x%5E4-9x%5E2-400%3D0%5C%5Cx%5E4-25x%5E2%2B16x%5E2-400%3D0%5C%5Cx%5E2%28x%5E2-25%29%2B16%28x%5E2-25%29%3D0%5C%5C%28x%5E2-25%29%28x%5E2%2B16%29)
When ![x^2-25=0](https://tex.z-dn.net/?f=x%5E2-25%3D0)
![x^2=25](https://tex.z-dn.net/?f=x%5E2%3D25)
Take square root of both sides
![x=\pm\sqrt{25}\\x=\pm5](https://tex.z-dn.net/?f=x%3D%5Cpm%5Csqrt%7B25%7D%5C%5Cx%3D%5Cpm5)
![when\ x^2+16=0\\x^2=-16\\x^2=16x^2\ (as\ i^2=-1)](https://tex.z-dn.net/?f=%20when%5C%20x%5E2%2B16%3D0%5C%5Cx%5E2%3D-16%5C%5Cx%5E2%3D16x%5E2%5C%20%28as%5C%20i%5E2%3D-1%29)
take square root of both side
![x=\pm\sqrt{ 16i^2}\\x=\pm4i](https://tex.z-dn.net/?f=x%3D%5Cpm%5Csqrt%7B%2016i%5E2%7D%5C%5Cx%3D%5Cpm4i)
32,000 x .09 = 2880
$2880 budgeted for clothes yearly
27/50 is the answer. Why? Because 54 and 100 are both divisible by 2. hope this helps
